Mental Health and Criminal Responsibility: Reforming Insanity Defenses

Abstract

The question of mental illness and responsibility has been one of the most controversial and subject to debate in criminal law, due to the need to make a balance in the concept of responsibility, public safety and protection of human basic rights. By removing the responsibility for the conduct of people with severe mental illness who are unable to appreciate the nature of their actions or understand what they are doing, the insanity defense is an important procedural tool in the legal system. In many places, however, outdated models set during the 1800s are the ones which are still used when there have been advances in psychiatric theory, forensic psychology and neuroscience. This paper critically reviews the development of the insanity defense and looks at some of the legal systems in place and how well they reflect the current scientific understanding of mental illness. The study uses a doctrinal and comparative legal research method, looks at the history of the insanity defence, examines the common link between medical and legal definitions of mental illness and discusses the different legal approaches used in the UK, USA, Canada, Australia and Pakistan. Additionally, the paper highlights some of the problems associated with effective use of insanity defence: outdated legal definitions, inconsistencies in psychiatric testimony, a lack of infrastructure for forensic mental health, procedural issues and deep social stigma around mental health. The study recommends a multi-disciplinary approach, using comparative analysis and recent legal scholarship that includes criminal law, forensic psychiatry and neuroscience and international human rights principles to achieve meaningful reform. It suggests reformation about the statutory concepts of legal insanity, improvement of forensic psychiatric facilities, judicial training, setting up mental health courts, and process protection of the mentally ill. The paper concludes that there is a need for prison sentences to reflect the realities of medical knowledge during the past few decades, as well as the core principles of justice, fairness and human dignity, while at the same time still providing adequate protection to the community.
